Every soccer mom and dad on Beacon Hill knows Larry McCann. He's the tall, lanky fellow who can be found before game season painting field lines in the dark with a camping light strapped to his head, the same guy who sorts out team uniforms, draws up schedules, sends constant e-mails, and shows up at games just to make sure everything is going all right. As president of Beacon Hill Youth Soccer, one of the many neighborhood clubs under the umbrella of the nonprofit Seattle Youth Soccer Association, it's all part of the job?an unpaid one that encompasses some 60 hours a week in the crunch time right before the fall season begins. What makes McCann's dedication so extraordinary, however, is that he doesn't have kids on the field. He used to?four of them, in fact?but the youngest is now in college. He says he never considered stopping when his children grew out of the program. "I'm a social worker," he says, adding that he works at Harborview Medical Center. "I understand the value to the community, particularly Beacon Hill. It's one of the only ways our diverse community can come together."?Nina Shapiro
